A partial lunar eclipse—the longest this century—will occur on November 19 and will be partly visible in Hong Kong

The longest lunar eclipse in 100 years will occur on November 19 and it will be partly visible in Hong Kong. The partial lunar eclipse will last for three hours and 28 minutes, which is longer than any other eclipses that happened or will happen this century, according to Nasa.

The Hong Kong Observatory says that the elevation of the moon will be rather low during the eclipse so the event can be best observed as places with an unobstructed view to the east and the northeast. Upon moonrise at 5:38 pm, the eclipse will already be in progress and visible in Hong Kong.

Then, the moon will leave the umbra—the Earth’s cone-shaped shadow—at 6:47 pm and the whole eclipse will end at 8:06 pm. Unfortunately, the maximum eclipse at 5:03 pm is not visible in Hong Kong.

When the sun, Earth and moon are aligned, the moon will enter the Earth’s shadow, resulting in a lunar eclipse. A partial lunar eclipse happens when part of the moon enters the umbra of the Earth. During this event, the moon appears in a reddish hue.

Hongkongers can watch the lunar eclipse online via a webcast organised by the Hong Kong Observatory, Hong Kong Space Museum, the Ho Koon Nature Education cum Astronomical Centre and Po Leung Kuk Nang Po Ling College. For more information on the weather conditions on November 19, you can refer to the nine-day weather forecast.
